DOI: 10.1016/j.scriptamat.2019.07.008
Abstract: Abstract A new single-phase face-centered-cubic (FCC) Co9Cr7Cu36Mn25Ni23 [atomic percent, similar hereinafter] high-entropy alloy (HEA) was prepared by arc melting. A uniform distribution of nanometer-sized precipitates was achieved. The tensile yield strength, ultimate tensile strength, and… read more here.

DOI: 10.1073/pnas.1914615117
Abstract: Significance Precipitates in a material are traditionally thought of as dislocation obstacles that lead to elevated strength and reduced ductility. In contrast, recent experiments suggest that nanoscale precipitates facilitate both high strength and large ductility.… read more here.
